IMPROVEMENT IN DIAL-FASTENINGS FOR WATCHES.

Specification forming part of Letters Patent No. 196,726, dated October30, 1877 applicationfiled April 14, 1876.

' ing drawing, in which;

Figure l is a plan view of a watch, showing' the pillar-plate and themanner of fastening the dial. Fig. 2 is a plan view with dial removed.Fig. 3 is a sectional view of the same.

Fi 4 is a view of the conical-shaped mit.

Corresponding letters show corresponding parts.

A represents the pillar-plate; B, a plate shaped so as to form theratchet-bridge, and extends out over the motion-Wheels, the bottoni ofthe plate being recessed for the wheels. O shows a projection or sleeve,which is struck up, leaving,I a hole, through which the socketofhour-wheelpasses. The outside of the sleeve has a thread cut on it tolit the conical-shaped nut b, which centers and holds the dial firmly inits proper place when screwed down. V-shaped notch, iitting on a pin orscrew, c, to prevent the dial from turning out of place.

By this manner of fastening, the dial can be removed without taking thewatch out of the case, which, in many instances, is very desirable, and,by doing` away with the dial-posts, obviates the danger of cracking,`the dial. It will be evident, also, that the dial can be made of anydesirable material, thereby securing cheapness and a variety in dials.Even a glass dial can be fastened securely andsafely in this manner.

Having` thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a watch, adial-fastening extending` from the pillar-plate up to andthrough the dial, substantially in the manner and for the purpose hereinset forth.

In testimony thatl I claim the foregoing I have hereunto set my handthis 22d day of July, 1876.
